Abstract
The Speech Intelligibility Index (SII) was used as a basis for predicting the performance of elderly hearing-impaired subjects on a speech-in-noise test. The standard SII calculation scheme was compared with modified schemes, and correlations were obtained between measured and predicted scores. The results suggested that a modified calculation scheme, which includes corrections for sensorineural hearing impairment and age, is appropriate for evaluating individual speech recognition scores Based on the results, a computer program has been developed for clinical prediction and evaluation of speech recognition scores.
